TargCentroidStep

class jwst.targ_centroid.TargCentroidStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)

Bases: JwstStep

Determine position of target source from TA verification image.

Create a Step instance.

Parameters:

namestr

The name of the Step instance. Used in logging messages and in cache filenames. If not provided, one will be generated based on the class name.

parentStep

The parent step of this step. Used to determine a fully-qualified name for this step, and to determine the mode in which to run this step.
